NAME
DESCRIPTION
Positive input voltage for the regulator. The internal loading on this input is typically 300
μ
A when-
ever the regulator is enabled, and less than 1
μ
filter capacitor is not required, it is recommended that a 1
μ
F ceramic capacitor be used for addi-
tional filtering and stability if this pin is greater than 2 inches from the main input filter.

GND
The negative reference for all voltages.
Enable/shutdown input. When EN is asserted high (V
EN
≥
1.6V), the regulator is enabled. When EN
is asserted low (V
EN
≤
0.4V), the regulator’s series pass transistor is forced into a high impedance
mode and an internal discharge resistance (500
) is applied to the output to quickly reduce the out-
put voltage to 0 volts.

PG
Power Good output. This is an open drain output and functions as a supply voltage supervisor for
the output voltage. It is asserted low when the output falls below 89% of its nominal value. This out-
put becomes inactive when V
OUT
remains above 97% of its nominal value for 1 to 5ms.
The regulated voltage output. An output capacitor of 1
μ
F is recommended to minimize any tran-
sient load disturbances under normal operating conditions. Additional output capacitance can be
used to further improve transient load response.
